Corosex (FloMag) pH Filter Media 20 Lb

Corosex FloMag Magnesium Oxide 20 Lb Box: Convenient 20 lb box useful for adding to calcite neutralizers. A typical 1.0 cubic foot may use 90 lbs of calcite and 10 lbs of Corosex. By neutralizing the free carbon dioxide in water, Corosex can correct acidic water conditions and render it less corrosive. Corosex, being a highly reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use.

Media consumption and pH correction are affected by a number of water chemical variables. Being soluble to acidity, Corosex will slowly dissolve and will need to be replenished periodically. On a per weight basis, magnesium oxide can neutralize much more acidity than can calcium carbonate, (five times as much). This results in greatly reduced chemical usage for the same pH correction. Please note, under certain low flowconditions, Corosex may over-correct and create a highly basic (high pH) condition. Under certain hardness conditions, pH correction can cause hardness mineralsto precipitate out of solution, resulting in cementing or solidification of the Corosex mineral bed.
